- added settings for screenshot path and image format - removed "Save" button, added "Cancel" and "Revert" buttons - added revert functionality - changed class design for cleaner functionality, separated ApplyChanges() into more functions to have finer control - added more error checking and fixed memory leaks (config_GetPsz() returns char*, not const char*!) - all settings are now correctly saved and restored - some more cosmetic changes modules/gui/beos/InterfaceWindow.h/.cpp - updated vlc way of saving settings to be on par with BeOS way and made it selectable in the code which way is used. However, the VideoSettings are still only savable in the BeOS way. - if dvd menus are used, the navigation menu enables a "Goto Menu" item. Unfortunately, I don't see a clean way to really detect the usage of dvd/dvdold in the currently playing stream. I wouldn't want to see if a playlist item has "dvd:" or "dvdold:" prepended at each interface update.
